摘要

本文试图改善矢量控制异步电动机驱动器的动态和稳态性能。基于微分几何概念的输入输出线性化和解耦技术已被用于将速度或转矩与磁链解耦。在磁链和速度环中设计了最优比例积分(P-I)控制器，以获得所需的动态和稳态响应。设计了一种新的转子磁链观测器来估计各种转速下的磁链。仿真结果表明，所设计的控制器与矢量控制器的驱动系统性能相当，且具有更大的灵活性。

Nonlinear controller for induction motor drive

An attempt has been made in the present work to improve the dynamic and steady state performances of the vector controlled induction motor (IM) drives. Input-output linearization and decoupling technique based on the concepts of differential geometry, has been used to decouple the speed, or torque from flux. Optimal proportional-integral (P-I) controllers in flux and speed loops are designed to obtain desired dynamic and steady state responses. A new rotor flux observer has been designed to estimate the flux at all speeds. Simulation results show that the performance of the drive system with the designed controller is comparable to that with vector controller and the proposed drive system is more flexible.
